Well that's encouraging considering all the talk the past couple days that both may be unavailable for game 1. Obviously it doesn't guarantee anything, but I don't think they'd have them out there already if it put them at risk of setbacks. Not sure what their level of participation is, but they have a picture of McCoy taking a hand-off from Tyrod.

Sounds like all the WR's are practicing too.
